EMI Calculator
Compute the fixed monthly EMI for any loan — principal, rate and tenure in, total interest and total repayment out, instantly.
EMI = P × r × (1+r)ⁿ ÷ ((1+r)ⁿ − 1) — the standard reducing-balance formula used by banks, where r is the monthly rate and n the number of months.

EMI Calculator
Enter the loan amount, annual interest rate and tenure in years or months to get the equated monthly installment plus the total interest you will pay over the life of the loan. The math is the standard reducing-balance formula that banks and NBFCs use.
Adjust any input and everything recalculates live, so you can compare a 15-year loan against a 20-year one, or see exactly what an extra 0.5% interest rate costs you each month.
Frequently asked questions
What formula does the EMI calculator use?
The standard reducing-balance formula: EMI = P × r × (1+r)ⁿ ÷ ((1+r)ⁿ − 1), where P is principal, r the monthly interest rate (annual ÷ 12 ÷ 100) and n the number of months. This is the same equation used by banks for home, car and personal loans.
Why is total interest so high early in the loan?
Interest each month is charged on the outstanding balance, which is largest at the start. Early EMIs are mostly interest and little principal; the mix flips as the balance shrinks. Prepaying early therefore saves much more interest than prepaying late.
Are fees and insurance included in the EMI?
No. Processing fees, insurance and any floating-rate changes are excluded — the result is the pure amortization EMI for the rate you enter. Your lender's sanction letter shows the final payable amount.
